Green Calder Grass by Janet Calder

The sixth in this series, Jessy finds herself the wife of Ty Calder who has divorced manipulative Tara. Just when things seem the brightest, Tara returns. Using the death of her father, Tara clings to Ty for comfort and support, threatening Jessy's happy home. All is not secure on the homefront, either, as drought threatens the ranch life. When the government serves notice that the Calder family will lose grazing and water rights to 10,000 acres, Chase and Ty consider their options. Ever the mischief maker, Tara weasels her way into their plans to save the ranch. Then Calder blood is spilled. Another great story in the continuing saga of the Calder family.
